IMPROVEMENT IN GRAIN-BINDERS.

Specification forming part of Letters Patent No. 204,989, dated June 18,1878 application filed January '7, 1878.

To all whom it may concern:

Be it known that I, ALEXANDER GREGORY MOINTOSH, of Atalissa, in thecounty of Muscatine and State of Iowa, have invented anew and usefulImprovement in Combined Reaper and Binder, of which the following is aspecification:

Figure 1, Sheet 1, is a top view of my improved machine. Fig. 2, Sheet1, is a detail top view of the shuttle and shuttle-carrier, the needlebeing shown in cross-section. Fig. 3, Sheet 2, is-a longitudinal sectionof the machine, taken through the broken line as w m 00, Fig. 1. Fig. 4,Sheet 3, is a cross-section of the machine, taken through the line 3 y,Fig. 1. Fig. 5, Sheet 3, is a detail section, showing the gavel cominginto position to be bound.

Similar letters of reference indicate corresponding parts.

The object of this invention is to furnish an improved machine whichshall be so constructed as to cut the grain, gather it into gavels, andbind it, the various operating.

parts receiving motion from the drive-wheel of the machine. 1

A represents the platform of a reaper, in bearings attached to whichrevolve the journals of the drive-wheel B. To one of the journals of thedrive-wheel B is attached a small chain-wheel, O, around which passesanendless chain, D. The chain D also passes around a larger chain-wheel,E, attached to the shaft F, which revolves in bearings attached to therear part of the frame of the platform A.

To the shaft F, inthe rear of the platform -A, is attached a drum, G, inthe face of which The bar J rests and slides upon bars K, at-' tachedtothe frame A, and its ends rest and slide in grooves formed incross-bars of the said frame A.

To the inner upper corner of the bar J is hinged a bar, L, to the upperside of which are attached the rake-teeth M. The teeth M, when in anerect position, project through slots in the platform A, so as to sweepthe cut grain across the said platform.

To the rear end of the rake bar or headLis attached a drum, N, to whichare attached'the ends of straps 0. The straps O are wound in oppositedirections around the drum N, and their other ends are attached to theopposite side parts of the frame A. r

The straps O are made of such a length as to turn the rake-teeth downand up at the proper time as the rake moves back and forth across theplatform, so that it may move back beneath the cut grain, and may carrythe said out grain with it as it moves forward. The strap 0, that turnsthe teeth M down, also presses the teethagainst the gavel, and holds itwhile the needle passes down to bind it.

To the shaft F is attached a large bevel-gear wheel, P, the teeth ofwhich mesh into the teeth of a smaller bevel-gear wheel, Q, attached tothe shaft R. The shaft R revolves in bearings attached to the frame ofplatform A, and its inner end enters the hollow post of the needle-armS, and has a crank-wheel, T, attached to it. 7 1.

The crank-pin of the wheel T enters a heart or other shaped groove orslotformed in the lower part of the vertical sliding bar V, or in ablock secured to said lower part.

-To the upper end of the sliding bar U is pivoted the end of a shortconnecting-bar, V, the other end of which is pivoted to the rear end ofthe lever W. The lever W is pivoted to the horizontal part of theneedle-arm S, and its forward end is curved downward, and to it ispivoted the upper end of a short connecting-bar, X, the lower end ofwhich is pivoted to the needle bar or holder Y. The needle bar or holderY works up and down in a guidesocket in the forwardvertical. part of theneedlearm S, and to the lower end of this bar is attached the needle Z.

In the needle Z, just above itspoint, is formed an eye to receive thecord or wire A and the outer side of the said needle is notched, asshown in Figs. 2, 3, and 4, for the shuttle B to pass through in forminga knot.

To the shaft It is attached a bevelgear To the outer journal of thedrive-wheel Bis attached a small chain-wheeLI, around which passes anendless chain, J. The endless chain J also passes around a smallchain-wheel, K,

pivoted to supports attached to the frame of A platform A.

To the chain-wheel K, or to its journal, is rigidly attached abevel-gear wheel, L, the teeth of which mesh into the teeth of thelarger bevel-gear wheel M, attached to the rear end of the shaft N. Theshaft N revolves in bearings in the parallel inclined bars 0, attachedto the frame A and to its other end is attached a chain-wheel, P, aroundwhich passes an endless chain, Q. The endless chain Q also passes arounda chain-wheel, B, attached to the end of a short shaft, S, which isplaced parallel with the shaft N, and revolves in bearings in theinclined bars 0.

To the shafts N S, between the inclined bars 0, are attached two cams,T, which, at each revolution, strike against the inclined bar U, placedbetween the inclined bars 0, and raise it, and then strike against thedownwardly-proj ectin g arms V, attached to the said bar U, and force itoutward.

The gearing is so arranged that the bar U V may be moved upward andoutward four times between the successive gavels. The inclined bar U Vis drawn downward and inward, as the cams release it, 'by the spiralspring W, one end of which is attached to the said bar V, and its otherend to a bar of the frame A.

To the bars 0 U 0 are attached teeth to take hold of the bundles, theteeth of bar U carrying the bundle upward and outward, and the teeth ofthe bars 0 keeping the said bundles from slipping back, and from beingdrawn back by the downward and inward movement of the bar U.

As each bundle drops from the upper end of the elevator O U 0 the cordsor Wires are cut off, to separate the bundles,vby the knife X. The rearend of the knife X is pivoted to the rear part of the platform-frame A,and the said knife is forced down to make a cut by a cam, Y, attached tothe end of the shaft F.

The knife X passes through a guide-slot in a post, Z, attached to theplatform-frame A, and is raised and held up until forced down by the camY by a spiral spring, A placed beneath it inthe slot of. the post Z.

B is an inclined plate or board, attached to the outer end of theplatform A, and slotted transversely from its inner edge to correspondwith the slots in the said platform A that the rake-teeth M projectthrough. The inclined board 13 receives the cut grain that falls uponthe outer end of the platform A, and causes it to slide inward, so as tobe out of the way of the rake-fingers M as they rise at the end of theiroutward movement.

To the top of the horizontal part of the needle-arm S is attached a pin,(3, to receive the spool D, that carries the needle cord or wire A.

From the spool D the cord or wire A passes through a guide-eye, E arounda tension de vice, F through the eye of the take-up arm G which projectsfrom a slot in the upright forward part of the needle-arm S, through aguide-eye, 11*, attached to the lower end of the said needle-arm, andthence to the needle Z. The needle-arm S should be provided with apresser-foot to press upon the gavel while being bound, and which shouldhave its side parts curved upward to prevent it from catching upon thestalks of grain.

The tension device F consists of two disks, flared from each other, andheld together and to the upright forward part of the needlearm S by athumb-screw, f and pressed to gether by a spiral spring, fflinterposedbetween the inner disk and the said part of the needle-arm, so that thetension may be regulated by tightening and loosening the said screw fWith this construction, as the machine is drawn forward the cut grainforms upon the slotted platform A, and is swept by the raketeeth Mbeneath the end of the needle-arm S, and into the loop formed by tyingthe ends of the needle cord or wire A andthe shuttle cord or wire Itogether, and hooking them upon a tooth of the elevator O U. The shuttleB then moves to the rearward, and the needle Z descends, passingbetween'the said shuttle B and the shuttle-cord 1 As the needle Zcontinues to descend the shuttle B passes forward through the notch inthe needle Z and above the needle-cord A The said needle then rises,passing out of the coil or loop of the shuttle-cord, and drawing theneedle-cord through it, thus forming a half -knot. The gavel is thenmoved up a little by the elevator 0 U, and a second half-knot is tied.The bundle is then carried up the elevator O U another step, and itsexpansion draws the two half-knots together, forming a firm knot. At thesame time the needle and shuttle form a third half-knot. The bundle isthen carried up the elevator another step, and a fourth half-knot isformed. As the fourth half-knot is formed the rake-teeth sweep anothergavel into place, the pressure of which draws the fourth and thirdhalf-knots together into a firm knot. The second bundle is then bound inthe same way,four half-knots being formed between each bundle and thenext one. As each bundle passes off the upper end of the elevator O Uthe knife X descends and cuts the cord between ,the two knots, andallows the bundle to drop to the ground or into a basket attached to-theside of the machine.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination, in a harvester, of the knife X andthe elevator U 0, as and for the purpose specified.

2. The combination, with the fixed toothbars 0 O, of the median movablebar U V, operated by the cams T T and spring W, as specified.

3. The combination of the two straps O, wound in opposite directions,with the hinged bar of the rake L M, for raising and lowering therake-teeth, and for pressing down the gavel while being bound,substantially as herein shown and described.

4. The combination, in a harvester, with the elevator and knife, of aknotting or binding mechanism that ties two knots between each sheaf, asand for the purpose specified.
